Can the U.S. Interbank Market Be Revived?

The U.S. interbank market essentially disappeared as the reserve supply dramatically increased after the 2007–2008 crisis. We build a model to study whether the interbank market can revive if the reserve supply decreases sufficiently. The market may not revive due to balance sheet costs associated with recent banking regulations. Although interbank volume may initially increase as reserves decline from abundant levels, the balance sheet costs may engender changes in market structure that completely replace interbank trading by nonbank lending to banks. This nonmonotonic response could lead to misleading forecasts about future interbank volumes.     

SHOULD THERE BE INTRADAY MONEY MARKETS?

In this article, we consider the case for an intraday market for reserves. We discuss the separate roles of intraday and overnight reserves and argue that an intraday market could be organized in the same way as the overnight market. We present arguments in favor of and against a market for intraday reserves when the marginal cost of overnight reserves is positive. We also consider how reserves should be supplied when the cost of overnight reserves is zero. In that case, the distinction between overnight and intraday reserves becomes blurred, raising an important question: What is the role of the overnight market?(JEL E44, E58)     

How Does Household Portfolio Diversification Vary with Financial Literacy and Financial Advice?

Household investment mistakes are an important concern for researchers and policymakers alike. Portfolio underdiversification ranks among those mistakes that are potentially most costly. However, its roots and empirical importance are poorly understood. I estimate quantitatively meaningful diversification statistics and investigate their relationship with key variables. Nearly all households that score high on financial literacy or rely on professionals or private contacts for advice achieve reasonable investment outcomes. Compared to these groups, households with below‐median financial literacy that trust their own decision‐making capabilities lose an expected 50 bps on average. All group differences stem from the top of the loss distribution.     

Housing Collateral and Entrepreneurship

We show that collateral constraints restrict firm entry and postentry growth, using French administrative data and cross‐sectional variation in local house‐price appreciation as shocks to collateral values. We control for local demand shocks by comparing treated homeowners to controls in the same region that do not experience collateral shocks: renters and homeowners with an outstanding mortgage, who (in France) cannot take out a second mortgage. In both comparisons, an increase in collateral value leads to a higher probability of becoming an entrepreneur. Conditional on entry, treated entrepreneurs use more debt, start larger firms, and remain larger in the long run.     

ADDICTIVE DRUG USE MANAGEMENT POLICIES IN A LONG‐RUN ECONOMIC MODEL*

A model of illicit, addictive drug use is proposed when users have foresight. Impacts of drug use penalties, penalties on drug use‐related crime, support for drug user rehabilitation as well as the effects of health‐related, harm‐minimisation policies are analysed. In the short run, government policies impact only on the drug use intensities of existing addicted and casual users. Longer term policy‐induced user‐cost changes impact on new user and addict numbers through their effect on recruitment into addiction and quit dynamics. Effects of policies on user numbers, usage intensities and impacts on long‐run social costs are analysed over this long‐term horizon. The model provides a setting for analysing the long‐run effects of illicit drug management policies on the social costs of illicit drug use and allows assessment of drug use abstinence and harm minimisation policy tradeoffs.
